Elementary module for concrete slabs formwork structure in building, has support beams connected together by transverse connection handles shifted in direction of length of beams, where each handle forms adjustable bridging unit of beams

摘要

The module has a frame (10) including two longitudinal support beams (11) that are connected together by two transverse connection handles (12) shifted in a direction of length of the beams, where each handle forms an adjustable bridging unit of the beams. Each handle is connected to the beams by its ends, and has a varying unit to vary the distance separating ends of the handles. Each handle adopts a shape of a toggle lever whose distance separating the ends is variable by adjusting an angle of flexion of the toggle lever.
